Abstract
Cyclo-olefins are converted in high yield to the corresponding chloro-nitroso dimers by dissolving the cyclo-olefin in liquid SO.sub.2 and contacting with NOCl while maintaining a substantially oxygen-free environment. Even higher yields are attained by controlling the gradual addition of the NOCl and by using a molar ratio of NOCl to cyclo-olefin of less than about 0.92:1.
